ATTACHMENT FOR GAS-FIXTURE KEYS.

SPECIFICATION forming part of Letters Patent No. 644,854, dated March 6, 1900.

Application filed May 2'7, 1899. Serial No. 718,617. (No model.) I

To ctZZ whom, it may cancer/t:

Be it known that I, PIERRIE ANTHONY FLORIMONT, a citizen of the United States, re siding at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Gas-FiX- tures, of which the following is a full and com plete specification, such as will enable those skilledin the art to which it appertains to make and use the same.

This invention relates to gas-fixtures, and has more particular reference to a device of this class provided with means for locking the valve thereof. I

With gas-fixtures in general use the valve is in constant danger of negligent and uni-ntentional operation, causing loss of gas and occasionally loss of life and property.

The object of the present invention is to provide the valve of a gas fixture with a sim- 2, an end view thereof, and Fig. 3 a section on the line 3 3 of Fig. 1.

-Referring more particularly to the drawings, I provide agas-fixture of the usual type and which consists of a pipe member 5, designed for attachment to the ordinary wallplug or other gas-supply connection and having at its outer end the burner 6. Transversely of and communicating with the pipe member 5 is the usual conical valve-casing 7, in which is seated the usual conical plug==valve 8, provided with a finger-piece or handle 9, and the valve 8 operates, in connection with the casing 7, to check, increase, and diminish the flow of gas through the pipe member 5 to the burner 6. The casing 7 is segmentally cutaway at its lower perimeter, as at 10, forming longitudinal shoulders 11, and the valve 8 is provided with a stop-pin 12, which'operates, in connection with the shoulders 11, to

limit the rotation ofthe valve 8 in the two closed positions thereof.

Thus far the describedfixture is as ordinarily constructed.

In the practice of myinvention I provide the valve 8 adjacent to the thumb-piece 9 other end of which engages the outer end portion of a catch 16, provided with side bearings 17, which are mounted upon the ends of the pin 14 exterior of thelugs 13, said catch extending within the plane of the edge of said .thumb-piece.- I

u The valve-casing 7 is provided uponthe cut-away edge portion 10 thereof with an an- -nular flange .18, which, as shown in the drawings, is of less depth and thickness than the shoulders 11 and terminates at each end. at a short distance from said shoulders.

The catch 16 is pivotally mounted in such position upon the valve-plug 8 that the inner end thereof registers radially with the pin 12 and extends beyond the same, resting normally upon the flange 18, but preferably not extending entirely to the inner edge of said flange to allow longitudinal adjustment of the plug-valve 8 by means of the conical nut 20 upon the end thereof. it Y The operation of my improved fixture will be evident from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof. When the gas is turned on and passing through the pipe member 5 and burner 63, the inner end 19 of the catch 16 rests upon the flange 18, being held thereon by the spring 15, and the pin 12 is out of engagement with either of the shoulders 11. When the gas is turned off, however, the pin 12 comes into engagement with one of saidjshoulders, and the inner end 19 of the catch 16 falls over said pin into the space between the adjacent shoulder 11 and the corresponding end of the flange 18 and locks the valve-plug 8 against rotation in any direction. It may be freed from this position, however, by simply operating the catch 16 against the spring 15 and raising the inner end 19 thereof onto the flange 18 or above the same, and the valve may then be readily turned as desired.

It is evident that many changes may be made in the construction and arrangement of the details of construction of my improved gas-fixture without departing from the principle' thereof.

The catch 16 may be caused to lock the valve 8 in any point of its rotation, and the spring 15 may be of any form, as well as the catch it-' self.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- In a gas-fixture, a valve-casing, a valve 0peratively mounted therein, and provided with a thumb-piece, a shoulder formed upon said casing and extending partially thereabout, a flange formed upon said casing between and ence of the subscribing witnesses, this 13th day of. May, 1899.

PIERRIE ANTHONY FLORIMONT.
